      Review & Installation Video

      I’m Justin with, and I’m going to be breaking down Pypes Violator Axle-back exhaust for the 2005-2010 Mustang GT. Even though the Violator uses what appears to be a traditional chambered muffler design, much like your factory exhaust or even the Magnaflow street, but instead of this muffler being filled with sound baffles, which can actually keep your sound levels down, the Violator from Pypes actually includes some sound deflectors into the muffler design, which give you a very aggressive exhaust note. Those rude sounding mufflers are constructed from thick 409 grade stainless steel, and exit out of these dual 4” polished tips, which feature a very cool rolled edge and slashed cut for a unique, quality look. Since the Violator bolts into the stock location without any modification, getting everything installed should only take you about an hour using a basic socket set. Now let’s hear how Pypes Violator series axle-back sounds compared to our factory exhaust.

      Product Information

      Features, Description, Reviews, Specs & Installation


      • Increases of Up to 10 More Horsepower
      • Aggressive Exhaust Note
      • Polished 304 Stainless Steel Construction

      Increase Performance. Bolting on a Pypes Violator Axle-Back to a stock 2005 to 2010 GT will yield an instant 5 to 10 horsepower gain! It features two Violator mufflers for Pypes ultimate in flow (and power gain) with an ultra aggressive sound!

      Aggressive Sound. Pypes Axle-Back features the Violator "Rude Sound" muffler that uses an internal louvered tube with mini sound deflector chambers that result of a unique aggressive sound.

      Quality Construction; OEM Fit. This Axle-Back system from Pypes is constructed from high quality polished 304 Stainless Steel and features a 4" rolled edge slash cut polished stainless tip, that exits in the stock location for aggressive Muscle Car looks.

      Application. The Pypes Violator Axle-Back is designed to fit the 2005-2010 GT, 2008-2009 Bullitt, and 2007-2010 Shelby GT500 Mustangs.

      Technical Note. Americanmuscle recommends adding the 2005+ Mustang 304 Stainless Steel Exhaust Hanger Kit from the drop down option above, to provide more strength, stability and a cleaner installed appearance. If you have a 2007 Mustang you may need the kit for correct installation.

        2 2007 GT500 - TravisP Installation Time: Afternoon

        Insane amount of drone in the car

        Would not recommend. Bought these because they were featured in AM video as being slightly louder than stock mufflers. At idle they sound pretty good, but between 1400 and 2100 RPM the drone inside the car is CRAZY loud. The passenger muffler also didn't fit properly, the hanger wires were slightly off so I had force the brackets into place to be screwed in. This resulted in the exhaust tip not sitting centered in the bumper cut out. Took me about 3 hours to install, majority of that time was spent trying to figure out what I was doing. Could definitely be done faster.

        Good Buy

        The product arrived in great condition no problems with packaging. Had the shop install them for a little less than $100. For that price I figured why even dig out the tools. Only took an hour to install and they sound great, I would prefer a little louder output.

        Great Pypes

        Not too loud but better than stock. If your looking for nice sounding pipes but want to hear yourself think when just cruzin down the street, these muffles are perfect.

        Fit was good, looks great. Clamps DO NOT tighten up on factory pipes. The sound is not what I expected. Factory mufflers sound better. These will be coming off!

        Great sound

        These axle-backs combined with a Pypes H-pipe really woke the car up and gave it the classic muscle car sound. Sounds even better after I added my Airaid CAI and tune. I cheated on the install and paid a shop to do it. Got everything welded up. Very pleased with the product. Shipping was fast and AM has excellent customer service.

        Love my new sound!

        I originally had long tube headers with off road x-pipe and the Pypes axle back deletes. It was so loud I set off car alarms and the local police force was looking for me daily. I installed these bad boys and I still have a great sound! Low and rumbling and people tell me how great my car sounds so all is well and good!
